Q: A 60Hz, 120V ac source supplies a group of loads as shown in Figure. If the voltage source is Vs=120V, find the apparent power of the source and the current Is. capacitor is connected parallel with load 1 and also parallel with load 2. connecting wire dissipates 1kW. load 1: 50kW with pf=0.7 lagging load 2: 20kW with pf=0.8 lagging capacitor: 30kVAR
